I like this book, It explains those important algorithms with rich details. It is easy for people to understand difficult algorithms. By the way, It was mailed to my home soon after I bought it in the web.

Good reference(Rating: 4)
This book is extremely well written. It covers a lot of ground, and it covers it deeply. Because of that, it might be a little hard for beginners; You'll need to skip over sections if you don't want to break your brain in half.

It's an excellent reference book. Some people think that a reference book is useless now because you can search on the internet, but I don't think you can find websites written as well as this book.
